Although intracerebral hemorrhage (ICH) volume and location are important predictors of outcome in adults, few data exist in children.
A consecutive cohort of children, including full-term newborns to those younger than 18 years of age with nontraumatic, acute ICH and head CT available for analysis were studied. Clinical information was abstracted via chart review. Hemorrhage volume was expressed as percentage of total brain volume (TBV) with large hemorrhage defined as >or=4% of TBV. Hemorrhages were manually traced on each head CT slice and volumes were calculated by multiplying by slice thickness. Location was classified as supratentorial or infratentorial. Logistic regression was used to identify predictors of poor neurological outcome, defined as a Glasgow outcome scale <or=2 (death or persistent vegetative state).
Thirty children were included, median age 6 years. Median ICH volume was 20.4 cm(3) and median ICH size as a percentage of TBV was 1.9%. Only 4 of 22 children with ICH <4% of TBV had poor outcomes, vs 5 of 8 children with ICH >or=4% of TBV (P=0.03). In multivariate analysis, hemorrhage >or=4% of TBV (OR, 22.5; 95% CI, 1.4-354; P=0.03) independently predicted poor outcome 30 days after ICH. In this small sample, infratentorial hemorrhage location and the presence of intraventricular hemorrhage did not predict poor outcome.
ICH volume predicts neurological outcome at 30 days in children, with worst outcome when hemorrhage is >or=4% of TBV. Location and ICH etiology may also be important. These findings identify children with ICH who are candidates for aggressive management and may influence counseling regarding prognosis.
虽然脑出血(ICH)的体积和位置是成人预后的重要预测指标,但关于儿童的相关数据较少。
对一组连续的儿童进行研究,包括足月新生儿至18岁以下非创伤性急性脑出血且有头颅CT可供分析的患儿。通过查阅病历提取临床信息。出血体积以全脑体积(TBV)的百分比表示,大出血定义为≥TBV的4%。在每张头颅CT切片上手动描绘出血区域,并通过乘以切片厚度计算体积。位置分为幕上或幕下。采用逻辑回归分析确定不良神经功能预后的预测因素,不良神经功能预后定义为格拉斯哥预后评分≤2分(死亡或持续性植物状态)。
纳入30例儿童,中位年龄6岁。中位脑出血体积为20.4 cm³,中位脑出血大小占TBV的百分比为1.9%。在22例脑出血体积<TBV 4%的儿童中,只有4例预后不良,而在8例脑出血体积≥TBV 4%的儿童中有5例预后不良(P = 0.03)。多因素分析显示,脑出血体积≥TBV的4%(比值比,22.5;95%可信区间,1.4 - 354;P = 0.03)是脑出血后30天不良预后的独立预测因素。在这个小样本中,幕下出血位置和脑室内出血的存在并不能预测不良预后。
脑出血体积可预测儿童30天时的神经功能预后,当出血体积≥TBV的4%时预后最差。出血位置和脑出血病因可能也很重要。这些发现有助于识别需要积极治疗的脑出血患儿,并可能影响预后咨询。
